Abstract
【選択図】図3
Description
===測定装置===
本実施形態に係る呼吸用湿熱交換体を設けた湿熱交換器が奏する効果を、肺シミュレータを用いて構成した測定装置によって、実験で確認した。図1に、本測定装置の模式的構成図を示す。
ポリウレタンフォームで略円筒状に形成した見かけ体積52.3cm3の蓄熱担体素材を用い、この担体には、患者側から順に密度が30、55、55、70kg/m3に設定された4つの層、第1層〜第4層を設け、各層の厚さは5.5mmとした。すなわち、サンプルAの蓄熱担体素材には、患者側から回路側へ向けて密度が高くなるように密度勾配が設定されている。蓄熱担体素材は、模擬呼吸気が流通する2個所の開口を設けた容器内に保持し、その容器を介して測定装置に接続した。サンプルBについても同様である。
次に、本発明の一実施例によるマスクについて、図13A、図13Bを参照して説明する。図13Aは本発明の実施例3に係るマスクの構成の一例を示す模式図、図13Bは図13Aのマスク本体の模式断面図である。
